[Qemu-devel] [RFC PATCH 13/56] pci: Make PCI addresses and sizes unsigne


From: Markus Armbruster
Subject: [Qemu-devel] [RFC PATCH 13/56] pci: Make PCI addresses and sizes unsigned in QAPI/QMP
Date: Mon, 7 Aug 2017 16:45:17 +0200

Sizes and addresses should use QAPI type 'size' (uint64_t).
PciMemoryRegion members @address and @size are 'int' (int64_t).
qmp_query_pci_regions() implicitly converts from pcibus_t,
i.e. uint64_t.

Change these PciMemoryRegion members to 'size'.

query-pci now reports sizes and addresses above 2^63-1 correctly
instead of their (negative) two's complement.

HMP's "info pci" already reported them correctly, because it
implicitly converted back to uint64_t.
